Engine not working properly screen green. take a long time to get clear picture have to turn tv off 4-5 times.

This is a set with bad picture tubes-not available except on rebuild basis.

Are you seeing bright green screen and then set shuts off?

Let me know so I can help--8 blinks is AKB error.

If you get green vertical bars or green dots in the picture but not in the menu screen (Digital board symptom)

Replace the STKs IC on the convergence PCB.

try adjusting your color tuners located inside tv behind speakers.

Hello,
Please call me 323-767-6030 and I will go through with you.

Please count the blinks if it is a repeating pattern and post the model number. This is a relatively common problem, but the solution is dependent upon the model number.
Thanks,
Dan

Sounds like a tuner or Video output problem. What make and model set do you have.

go into menu turn color off see if you have a black and white picture if not adjust red,green, and blue screen drive on controls in back of tv you have red, green, blue it will have focus /screen controls cover each tube do one at a time blue focus and screen drive adjust to clear blue picture do all 3 tubes, then adjust them to where you have a black&white picture once this is done turn color controll back on.Thank You for using FixYa and Have a Nice Day.

this is degaussing problem

keep tv off for half an hour and if you have changed the direction keep it as it was.

if any magnetic thing is there near to tv remove it like speaker or headphone etc.

hope this will help.

Do not have a clue without a model number and make. Are we to be fortune tellers here too?
